<a name="GtkCellLayout.description"></a><h2>Description</h2>
<p>
<a class="link" href="GtkCellLayout.html" title="GtkCellLayout"><span class="type">GtkCellLayout</span></a> is an interface to be implemented by all objects which
want to provide a <span class="type">GtkTreeViewColumn-like</span> API for packing cells, setting
attributes and data funcs.
</p>
<p>
One of the notable features provided by implementations of GtkCellLayout
are <span class="emphasis"><em>attributes</em></span>. Attributes let you set the properties
in flexible ways. They can just be set to constant values like regular
properties. But they can also be mapped to a column of the underlying
tree model with <a class="link" href="GtkCellLayout.html#gtk-cell-layout-set-attributes" title="gtk_cell_layout_set_attributes ()"><code class="function">gtk_cell_layout_set_attributes()</code></a>, which means that the value
of the attribute can change from cell to cell as they are rendered by the
cell renderer. Finally, it is possible to specify a function with
<a class="link" href="GtkCellLayout.html#gtk-cell-layout-set-cell-data-func" title="gtk_cell_layout_set_cell_data_func ()"><code class="function">gtk_cell_layout_set_cell_data_func()</code></a> that is called to determine the value
of the attribute for each cell that is rendered.
</p>
<div class="refsect2">
<a name="GtkCellLayout-BUILDER-UI"></a><h3>GtkCellLayouts as GtkBuildable</h3>
<p>
Implementations of GtkCellLayout which also implement the GtkBuildable
interface (<a class="link" href="GtkCellView.html" title="GtkCellView"><span class="type">GtkCellView</span></a>, <a class="link" href="GtkIconView.html" title="GtkIconView"><span class="type">GtkIconView</span></a>, <a class="link" href="GtkComboBox.html" title="GtkComboBox"><span class="type">GtkComboBox</span></a>, <a class="link" href="GtkComboBoxEntry.html" title="GtkComboBoxEntry"><span class="type">GtkComboBoxEntry</span></a>,
<a class="link" href="GtkEntryCompletion.html" title="GtkEntryCompletion"><span class="type">GtkEntryCompletion</span></a>, <a class="link" href="GtkTreeViewColumn.html" title="GtkTreeViewColumn"><span class="type">GtkTreeViewColumn</span></a>) accept GtkCellRenderer objects
as &lt;child&gt; elements in UI definitions. They support a custom
&lt;attributes&gt; element for their children, which can contain
multiple &lt;attribute&gt; elements. Each &lt;attribute&gt; element has
a name attribute which specifies a property of the cell renderer; the
content of the element is the attribute value.
